GENERAL DESCRIPTION
The Model CN63200 Controller accepts signals from a variety of temperature
sensors (thermocouple or RTD), while the Model CN63400 Controller accepts
either a 0 to 10 VDC or 0/4 to 20 mA DC input signal. Both controllers can
provide an accurate output control signal (time proportional or DC Analog
Output) to maintain a process at a setpoint value. Dual 4-digit displays allow
viewing of the process/temperature and setpoint simultaneously. Front panel
indicators inform the operator of the controller and output status. The
comprehensive programming allows these controllers to meet a wide variety of
application requirements.
MAIN CONTROL
The controller operates in the PID Control Mode for both heating and
cooling, with on-demand auto-tune, that establishes the tuning constants. The
PID tuning constants may be fine-tuned through the front panel and then locked
out from further modification. The controller employs a unique overshoot
suppression feature, that allows the quickest response without excessive
overshoot. Switching to Manual Mode provides the operator direct control of the
output. The controller may also be programmed to operate in On/Off mode with
adjustable hysteresis.
ALARMS
Optional alarm(s) can be configured independently for absolute high or low
acting with balanced or unbalanced hysteresis. They can also be configured for
deviation and band alarm. In these modes, the alarm trigger values track the
setpoint value. Adjustable alarm hysteresis can be used for delaying output
response. The alarms can be programmed for Automatic or Latching operation.
A selectable standby feature suppresses the alarm during power-up until the
temperature stabilizes outside the alarm region.

FRONT PANEL PROGRAMMING
ANALOG OUTPUT OPTION
The optional DC Analog Output (10 V or 20 mA) can be configured and
scaled for control or re-transmission purposes. The programmable output update
time reduces valve or actuator activity.
CONSTRUCTION
The controller is constructed of a lightweight, high impact, black plastic
textured case and bezel with a clear display window. The front panel meets
NEMA 4X/IP65 specifications when properly installed. In applications that do
not require protection to NEMA 4X, multiple controllers can be stacked
horizontally or vertically. Modern surface-mount technology, extensive testing,
plus high immunity to noise interference makes the controller extremely reliable
in industrial environments.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use the controller to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the controller. An independent and redundant
temperature limit indicator with alarm outputs is strongly recommended.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
CAUTION: Risk of electric shock.

EMC INSTALLATION GUIDELINES
Although Red Lion Controls Products are designed with a high degree of
immunity to Electromagnetic Interference (EMI), proper installation and wiring
methods must be followed to ensure compatibility in each application. The type
of the electrical noise, source or coupling method into a unit may be different
for various installations. Cable length, routing, and shield termination are very
important and can mean the difference between a successful or troublesome
installation. Listed are some EMI guidelines for a successful installation in an
industrial environment.
1. A unit should be mounted in a metal enclosure, which is properly connected
to protective earth.
2. Use shielded cables for all Signal and Control inputs. The shield connection
should be made as short as possible. The connection point for the shield
depends somewhat upon the application. Listed below are the recommended
methods of connecting the shield, in order of their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end where the
unit is mounted.
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is over 1 MHz.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors, feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run through metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter. Also, Signal or Control cables within
an enclosure should be routed as far away as possible from contactors, control
relays, transformers, and other noisy components.
4. Long cable runs are more susceptible to EMI pickup than short cable runs.
5. In extremely high EMI environments, the use of external EMI suppression
devices such as Ferrite Suppression Cores for signal and control cables is
effective. The following EMI suppression devices (or equivalent) are
recommended:
Fair-Rite part number 0443167251 (RLC part number FCOR0000)
Line Filters for input power cables:
Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)
6. T o protect relay contacts that control inductive loads and to minimize radiated
and conducted noise (EMI), some type of contact protection network is
normally installed across the load, the contacts or both. The most effective
location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide
varistor (MOV) across an AC inductive load is very effective at reducing
EMI and increasing relay contact life.
b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor
switch, care must be taken not to exceed the breakdown voltage of the
transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid state
outputs have internal zener diode protection. However external diode
protection at the load is always a good design practice to limit EMI.
Although the use of a snubber or varistor could be used.
RLC part numbers: Snubber: SNUB0000
Varistor: ILS11500 or ILS23000
7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be connected
to an output common. This would cause EMI on the sensitive input common,
which could affect the instrument’s operation.

To insure proper operation, the Analog Output jumpers must be set to the
same range selected in programming Module 2-OP. The default jumper
setting is for 20 mA. The default setting in Module 2-OP is 4-20 mA.
To access the jumpers, insert a flat-blade screwdriver between the
front panel and the side case slot. This should disengage the
top and bottom front panel latches from the case
grooves. Pull the front panel assembly with the
controller boards out of the case. The
jumpers are located inside the

CUT-OUT
IF NEMA 4 IS NOT REQUIRED,
THIS PANEL MATERIAL MAY BE REMOVED.
The CN63200 and CN63400 controllers meet NEMA 4X/IP65 requirements
for indoor use to provide a watertight seal in steel panels with a minimum
thickness of 0.09", or aluminum panels with
a minimum thickness of 0.12". The
controllers are designed to be mounted
into an enclosed panel. The bezel
assembly must be in place during
installation of the controller.
Multiple Controller Stacking
The controller is designed to allow for close spacing of multiple controllers
in applications that do not require protection to NEMA 4X. Controllers can be
stacked either horizontally or vertically. For vertical stacking, install the panel
latch with the screws to the sides of the controller. For horizontal stacking, the
panel latch screws should be at the top and bottom of the controller. The
minimum spacing from centerline to centerline of controllers is 1.96" (49.8
mm). This spacing is the same for vertical or horizontal stacking.
Note: When stacking
controllers, provide
adequate panel
ventilation to ensure
that the maximum
operating temperature
range is not exceeded.
Instructions:
1. Prepare the panel cutout to the proper dimensions.
2. Remove the panel latch from the controller. Discard the cardboard sleeve.
3. Carefully remove the center section of the panel gasket and discard. Slide the
panel gasket over the rear of the controller, seating it against the lip at the
front of the case.
4. Insert the controller into the panel cutout. While holding the controller in
place, push the panel latch over the rear of the controller, engaging the tabs
of the panel latch in the farthest forward slot possible.
5. To achieve a proper seal, tighten the panel latch screws evenly until the
controller is snug in the panel, torquing the screws
to approximately 7 in-lb (79 N-cm). Overtightening
can result in distortion of the controller, and
reduce the effectiveness of the seal.
Note: The installation location of the controller is
important. Be sure to keep it away from heat
sources (ovens, furnaces, etc.) and away from
direct contact with caustic vapors, oils, steam, or
any other process by-products in which exposure
may affect proper operation.

3.0 Wiring the Controller
WIRING CONNECTIONS
All wiring connections are made to the rear screw terminals. When wiring the
controller, use the numbers on the label and those embossed on the back of the
case, to identify the position number with the proper function.
All conductors should meet voltage and current ratings for each terminal.
Also, cabling should conform to appropriate standards of good installation, local
CONTROLLER POWER CONNECTIONS
For best results, the power should be relatively “clean” and within
the specified limits. Drawing power from heavily loaded circuits or
from circuits that also power loads that cycle on and off should be
avoided. It is recommended that power supplied to the controller be
protected by a fuse or circuit breaker.
codes and regulations. It is recommended that power (AC or DC) supplied to the
controller be protected by a fuse or circuit breaker. Strip the wire, leaving
approximately 1/4" (6 mm) bare wire exposed (stranded wires should be tinned
with solder). Insert the wire under the clamping washer and tighten the screw
until the wire is clamped tightly.

INPUT CONNECTIONS
For two wire RTDs, install a copper sense lead of the same gauge and length
as the RTD leads. Attach one end of the wire at the probe and the other end to
input common terminal. Complete lead wire compensation is obtained. This is
the preferred method. If a sense wire is not used, then use a jumper. A
temperature offset error will exist. The error may be compensated by
programming a temperature offset.

controller is in Automatic Mode, this value is read only. When the controller is
placed in Manual Mode, the value can be changed, activated and stored by
pressing the arrow keys. For more details on % Output Power, see Control
Mode Explanations.
OUTPUT POWER OFFSET
When the Integral Time is set to zero and the controller is in the Automatic
Mode, this parameter will appear after % Output Power. It is also shown with
the %PW annunciator illuminated. The power offset is used to shift the
proportional band to compensate for errors in the steady state. If Integral Action
is later invoked, the controller will re-calculate the internal integral value to
provide “bumpless” transfer and Output Power Offset will not be necessary.
to
INTEGRAL TIME
Integral action shifts the center point position of the proportional band to
eliminate error in the steady state. The higher the integral time, the slower the
response. The optimal integral time is best determined during PID Tuning. If
time is set to zero, the previous Integral output power value is maintained.
Offset Power can be used to provide Manual Reset.
Derivative time helps to stabilize the response, but too high of a derivative
time, coupled with noisy signal processes, may cause the output to fluctuate too
greatly, yielding poor control. Setting the time to zero disables derivative action.
On models with alarms, the value for Alarm 1 can be entered here. The value

The setpoint ramp rate can reduce sudden shock to the process and reduce
overshoot on startup or after setpoint changes, by ramping the setpoint at a
controlled rate. R annunciator flashes while ramping. With the CN63200, the
ramp rate is always in tenths of degrees per minute, regardless of the resolution
chosen for the process display. With the CN63400, the ramp rate is in leastsignificant (display units) digits per minute. A value of 0.0 or 0 disables setpoint
ramping. Once the ramping setpoint reaches the target setpoint, the setpoint ramp
rate disengages until the setpoint is changed again. If the ramp value is changed
during ramping, the new ramp rate takes effect. If the setpoint is ramping prior to
starting Auto-Tune, the ramping is suspended during Auto-Tune and then
resumed afterward. Deviation and band alarms are relative to the target setpoint,
not the ramping setpoint. A slow process may not track the programmed setpoint
rate. At power up, the ramping setpoint is initialized at the ambient temperature/
process value.

To scale the controller , two scaling points are necessary. Each scaling point has
a coordinate pair of Display Values and Input Values. It is recommended that the
two scaling points be at the low and high ends of the input signal being measured.
Process value scaling will be linear between and continue past the entered points
to the limits of the input range. (Factory settings example will display 0.0 at 4.00
mA input and display 100.0 at 20.00 mA input.) Reverse acting indication can be
accomplished by reversing the two signal points or the Display value points, but
not both. If both are reversed, forward (normal) acting indication will occur. In

The Cycle Time is entered in seconds with one tenth of a second resolution.
It is the total time for one on and one off period of the time proportioning
control output O1. With time proportional control, the percentage of power is
converted into an output on-time relative to the cycle time value set. (If the
controller calculates that 65% power is required and a cycle time of 10.0
seconds is set, the output will be on for 6.5 seconds and off for 3.5 seconds.)
For best control, a cycle time equal to one-tenth or less, of the natural period of
oscillation of the process is recommended. When using the Analog Output
signal for control, the Cycle Time setting has no effect. If the O1 output is not
being used, a cycle time of 0 can be entered to prevent the output and indicator
from cycling.
CONTROL ACTION
This determines the control action for the PID loop. Programmed for direct
action (cooling), the output power will increase if the Process value is above the
Setpoint value. Programmed for reverse action (heating), the output power
decreases when the Process Value is above the Setpoint Value. For heat and cool
applications, this is typically set to reverse. This allows O1 or A1 (models with
Analog Output) to be used for heating, and A2/O2 to be used for cooling.

In Automatic mode, an energized alarm turns off automatically after the

energized alarm requires an F1 key or user input alarm reset to turn off. After an
alarm reset, the alarm remains reset off until the trigger point is crossed again.
ALARM STANDBY ALARM 1
Standby prevents nuisance (typically low level) alarms after a power up or
setpoint change. After powering up the controller or changing the setpoint, the
process must leave the alarm region (enter normal non-alarm area of operation).
After this has occurred, the standby is disabled and the alarm responds normally
until the next controller power up or setpoint change.
The alarm values are entered as process units or degrees. They can also be
entered in the Display or Hidden Loops. When the alarm is configured as
deviation or band acting, the associated output tracks the Setpoint as it is
changed. The value entered is the offset or difference from the Setpoint.

COOLING
CYCLE
To enable Cooling in Heat/Cool applications, the Alarm 2 Action must first
be set for Cooling. (For CN63400 Controllers, the cooling output is sometimes
referred to as secondary output.) When set to cooling, the output no longer
operates as an alarm but operates as a cooling output. The O2 terminals are the
same as A2, however a separate O2 annunciator indicates Cooling Operation.
Cooling output power ranges from -100% (full cooling) to 0% (no cooling,
unless a heat/cool overlap is used). The Power Limits in Output Module
also limit the cooling power. In applications requiring only a Cooling output,
the main 01 output should be used.

This defines the overlap area in which both heating and cooling are active
(negative value) or the deadband area between the bands (positive value). If a
heat/cool overlap is specified, the percent output power is the sum of the heat
power (O1) and the cool power (O2). If Relative Gain is zero, the cooling
output operates in the On/Off Control Mode, with the On/Off Control
Hysteresis in Output Module becoming the cooling output hysteresis.
The function of Deadband is illustrated in the Control Mode Explanations. For
most applications, set this parameter to 0.0 prior to starting Auto-Tune. After
the completion of Auto-Tune, this parameter may be changed.
RELATIVE GAIN

This defines the gain of the cooling relative to the heating. It is generally set
to balance the effects of cooling to that of heating. This is illustrated in the Heat/

CALIBRATION
The controller is fully calibrated from the factory. Recalibration is
recommended every two years by qualified technicians using appropriate
equipment. Calibration may be performed by using the front panel.
Calibration may be aborted by disconnecting power to the controller before
exiting Factory Service Module . In this case, the existing calibration
settings remain in effect.
Note: Allow the controller to warm up for 30 minutes minimum and follow
the manufacturer’s warm-up recommendations for the calibration source or
measuring device.
Millivolt Calibration (CN63200)
Millivolt calibration requires a precision voltage source with an accuracy of
0.03% (or better) connected to terminals 8 (comm.) and 9 (+). When calibrating
the input, the millivolt calibration must be performed first, then the Cold Junction
or RTD Resistance.
PROMPT APPLY FRONT PANEL ACTION
Cold Junction (CN63200)
Cold Junction calibration requires a thermocouple of known accuracy of
types T, E, J, K, C or N (connected to terminals 8 and 9) and a calibrated
external reference thermocouple probe measuring in °C with resolution to
tenths. The two probes should be brought in contact with each other or in some
way held at the same temperature. They should be shielded from air movement
and allowed sufficient time to equalize in temperature. (As an alternative, the
CN63200 thermocouple may be placed in a calibration bath of known
temperature.) If performing the millivolt calibration prior, verify that the correct
input type is configured in Input Module before performing the following
procedure. (After the millivolt calibration the controller will default to type J.) If
using RTD only, the cold junction calibration need not be performed.

PID CONTROL
In PID Control, the controller processes the input and then calculates a
control output power value by use of a modified Proportional Band, Integral
Time, and Derivative T ime control algorithm. The system is controlled with the
new output power value to keep the process at the setpoint. The Control Action
for PID Control can be set to reverse for heating (output on when below the
setpoint) or direct for cooling (output on when above the setpoint) applications.
For heat and cool systems, the heat (O1) and cool (O2) outputs are both used.
The PID parameters can be established by using Auto-Tune, or they can be
Manually tuned to the process.

TIME PROPORTIONAL PID CONTROL
In Time Proportional applications, the output power is converted into output
On time using the Cycle Time. For example, with a four second cycle time and
75% power, the output will be on for three seconds (4 × 0.75) and off for
one second.
The cycle time should be no greater than 1/10 of the natural period of
oscillation for the process. The natural period is the time it takes for one
complete oscillation when the process is in a continuously oscillating state.
LINEAR PID CONTROL
In Linear PID Control applications, the Analog Output Assignment is set
to % Output Power, . The Analog Low Scaling, , is set to 0.0 and the
Analog High Scaling, , is set to 100.0. The Analog Output will then be
proportional to the PID calculated % output power for Heat or Cooling per the
Control Action . For example, with 0 VDC to 10 VDC (scaled 0 to 100%)
and 75% power, the analog output will be 7.5 VDC.
pid tuning explAnAtionS
MANUAL CONTROL MODE
In Manual Control Mode, the controller operates as an open loop system
(does not use the setpoint and process feedback). The user adjusts the percentage
of power through the % Power display to control the power for Output O1.
When Alarm 2 is configured for Cooling (O2), Manual operation provides 0 to
100% power to O1 (heating) and -100 to 0% power to O2 (Cooling). The Low
and High Output Power limits are ignored when the controller is in Manual.
MODE TRANSFER
When transferring the controller mode between Automatic and Manual, the
controlling outputs remain constant, exercising true “bumpless” transfer. When
transferring from Manual to Automatic, the power initially remains steady, but
Integral Action corrects (if necessary) the closed loop power demand at a rate
proportional to the Integral Time.
AUTOMATIC CONTROL MODE
In Automatic Control Mode, the percentage of output power is automatically
determined by PID or On/Off calculations based on the setpoint and process
feedback. For this reason, PID Control and On/Off Control always imply
Automatic Control Mode.
AUTO-TUNE
Auto-Tune is a user-initiated function that allows the controller to
automatically determine the Proportional Band, Integral Time, Derivative T ime,
Digital Filter, Control Output Dampening Time, and Relative Gain (Heat/Cool)
values based upon the process characteristics. The Auto-Tune operation cycles
the controlling output(s) at a control point three-quarters of the distance
between the present process value and the setpoint. The nature of these
oscillations determines the settings for the controller’s parameters.
Prior to initiating Auto-T une, it is important that the controller and system be
first tested. (This can be accomplished in On/Off Control or Manual Control
Mode.) If there is a wiring, system or controller problem, Auto-Tune may give
incorrect tuning or may never finish. Auto-Tune may be initiated at start-up,
from setpoint or at any other process point. However, ensure normal process
conditions (example: minimize unusual external load disturbances) as they will
have an effect on the PID calculations.
Start Auto-Tune
Below are the parameters and factory settings that affect Auto-Tune. If these
setting are acceptable then Auto-Tune can be started just by performing two
steps. If changes are needed, then they must be made before starting Auto-T une.

Auto-Tune Progress
The controller will oscillate the controlling output(s) for four cycles. The
bottom display will flash the cycle phase number. Parameter viewing is
permitted during Auto-Tune. The time to complete the Auto-Tune cycles is
process dependent. The controller should automatically stop Auto-Tune and
store the calculated values when the four cycles are complete. If the controller
remains in Auto-Tune unusually long, there may be a process problem. AutoTune may be stopped by entering in Auto-Tune Start .

Page 24
PID Adjustments
In some applications, it may be necessary to fine tune the Auto-Tune
calculated PID parameters. To do this, a chart recorder or data logging device is
needed to provide a visual means of analyzing the process. Compare the actual
process response to the PID response figures with a step change to the process.
Make changes to the PID parameters in no more than 20% increments from the
starting value and allow the process sufficient time to stabilize before evaluating
the effects of the new parameter settings.

4. Set the Output Cycle Time [CYCt] in Output Module to no higher than
one-tenth of the process time constant (when applicable).
5. Place the controller in Manual Control Mode in the Hidden Loop
and adjust the % Power to drive the process value to the Setpoint value.
Allow the process to stabilize after setting the % Power. Note: must be
